HARROW.

SPECIFICATION forming part of Letters Patent No. 324,168, dated August 11, 1885.

Application filed May 2, 1885. (No model.)

To all whom it may concern.-

Be it known that I, ENooH JOHN ROGERS, a citizen of the United States, and a resident of Memphis, in the county of Macomb and State of Michigan, have invented certain new and useful Improvements in Harrows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my improved harrow,showing the same in position for operation. Fig. 2is a perspective view of one of the holders for attaching the teeth to the barrow-bars at the points at which the latter cross each other. Fig. 3 is a horizontal sectional view of the said holder. Fig. 4 is a vertical transverse sectional view taken on the line was in Fig. 3. Fig. 5 is a perspective View of one of the single tooth-holders. Fig. 6 is a horizontal sectional view of the latter, and Fig. 7 is a vertical sectional view taken on the line 3 y in Fig. 6.

The same letters refer to the same parts in all the figures.

This invention relates to that class of harrows which are constructed wholly of iron; and it consists in certain improvements in the construction of the same, having for their object to provide a device which shall possess superior advantages in point of simplicity, durability, and general efficiency.

With these ends in view the invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A A designate the front sections of my improved harrow, and B B are the rear sections of the same, which latter are connected with the front sections by means of links 0 0, while the front sections are connected by chains D D with the draw-bar E. The rear ends of the rear sections are also connected with each other by means of chains F F, so that all of the sections of the harrow shall have the greatest possible freedom of motion.

In lieu of constructing the harrow-sections of single iron bars, as is commonly done, the sections of my improved harrow are made up of links G, each consisting of two parallel bars, H H. The links of the front sections are closed at both ends, while those of the rear sections are only closed at their front ends. Both ends of the rear sections are connected by means of crossbars, and only the front ends of the front sections are so connected, thus saving one cross-bar for each front section, and at the same time a greater degree of elasticity is thus secured than if extra crossbars were used. The ends of these links are readily connected by the links 0 G, and they will also be found convenient for the attachment of the connecting-chains, as herein described. At the points where the links G G cross each other they are connected by means of the clips I, illustrated in Figs. 2, 3, and4 of the drawings. These clips consist of metallic blocks having transverse openings J and K, one above the other, as shown, and at any desired angle to each other, for the passage of the upper and lower links respectively. The said clip is also provided with a vertical opening, L, through which the tapering tooth M may be driven, the inner sides of the bars H, forming the upper link, being provided with notches N for the accommodation of the edges of the tooth. When the latter is driven into place it spreads the bars H, forcing the links somewhat apart, causing them to bind tightly in the clip, which therefore serves to connect the bars of the harrow-section, and also to connect the teeth to the latter.

For the purpose of attaching the teeth at points where the links or bars G G do not cross each other, I employ the clips or holders shown in Figs. 5, 6, and 7 of the drawings, which are provided only with a transverse opening for the passage of the link and a vertical perforation for the passage of the tooth, as shown, respectively, at O and P. When the tooth is driven it forces the sides of the link apart, thus causing the parts to bind firmly together.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood.

IOO

The construction issimpleand inexpensive. It maybe made fully as light as when the barrowseetions are made up 01' single bars, and the parts may be joined more firmly and durably than when single bars are used.

I-Iavingthus described my invention, 1' claim and desire to secure by Letters Patent ot' the United States- 1. In a harrow, the combination, with a cross-beam, ofa series of trout sections secured thereto, the front ends of said sections being connected by a cross-bar and the rear ends disconnected, and a series of rear sections connected at their front and rear portions by crossbars and connected at their rear portions to each other and at their front portions to the front sections, all of said sections being provided with a number of clips and teeth, substantially as and for the purpose set forth.

2. In a barrow, the combination, with a I cross-beam, of a series of frontseetionssecured thereto, each of said sections being composed ot'links consisting of parallel bars closed at both I ends and secured together by means of crossbars at their front ends, a series of rear seetlons composed of links consisting of parallel bars i closed at their front ends and secured together I attheir front and rear portions by cross-bars, I all of said sections being provided with clips i and teeth, and links for connecting said See- 5 tions, substantially as and for the purpose set forth. i In testimony that I claim the foregoing as my own I have hereunto allixed my signature I in presence ot' two witnesses.
